Resilient skid for shock mounted packaging



July l1, 1967 J. J. WHYIRLEIN RESILIENT SKID FOR SHOCK MOUNTED PACKAGING Filed Oct. 6, 1965 United States Patent O 3,330,521 RESILIENT SKID FOR SHOCK MOUNTED PACKAGING John J. Whirlein, Langhorne, Pa., assignor to the United States of America as represented by the Secretary of the Air Force Filed Oct. 6, 1965, Ser. No. 493,599 1 Claim. (Cl. 248-358) ABSTRACT OF THE DISCLOSURE A resilient skid mounted under a container and incorporated as part thereof including an extension of the side wall of the container as one side restraint and a pair of angle irons attached to the lioor of the container acting as end restraints with a wooden block arranged to act as the other side restraint. A pair of angle irons are attached to the sides to hold a resilient shock absorbing pack while permitting a Wooden foot to extend through as a bearing surface.

This invention relates generally to skids and more particularly to a resilient skid for shock mounted packaging.

Ordinarily when a heavy, delicate object must be transported from one location to another the item is packed in an outer container made of some strong material such as metal or wood then further packed in a resilient material to prevent damage or breakage. Obviously the space required to transport and store such a bulky pack` age is greatly increased and hence the cost of storage and transportation is proportionately increased.

It is therefore the purpose as well as an object of this invention to provide improved impact protection for packaged items by the utilization of resilient skids under the container.

It is a further Iobject of this invention to provide a novel package for transportation of articles.

It is still another object of this invention to provide a novel skid, incorporated as part of a transportable container construction.

It is still a further object of this invention to provide a new shock mounted container.

It is another object of this invention to provide an adjustable shock mounting means for containers.

It is another object of this invention to provide irnproved shock isolation for containers by damping lateral components yof shock and permitting lateral deections.

These and other advantages, features and objects of the invention will become -more apparent from the following description taken in connection with the illustrative embodiments in the accompanying drawings, wherein:

FIGURE l is an end elevation view partly in section of the skid of this invention; and

FIGURE 2 is a side view of the container with the skid means attached thereto.

Besides offering greater protection to the articles being transported hard mounting of the item to the container greatly simplies the design of the container as well as affording shock protection to the container. In addition the deflection clearances between containers is eliminated Patented July 11, 1967 which in effect further reduces the effective size of the container.

A further advantage to shock mounting the container is that it will eliminate a comm-on and often expensive to correct problem correlated with shock mounting, in that when the container is tied down during shipment the novel skids of this invention will be restricted from vibrating to peak amplitude at resonant frequencies causing damage to the container contents.

Referring now to FIGURE 1, the oating wooden foot assembly 10 is made up of two juxtaposed wooden numbers 12 and 16 which are securely fastened together against relative movement. Bordering the wooden foot on three sides are resilient high-energy absorbing buifers 18, 20 and 22 such as the Armstrong Resilo-Pak 400. The buifers are slightly compressed when installed in order that all members may maintain the correct relative position. The mounting thus provides the wooden foot with a resilient bearing on both the vertical as well as lateral direction.

On the outside of the buffer 22 is the side panel of the container 24 which extends downward past the iioor of the container 26 to provide a bearing-reaction surface for the butter in the lateral direction. Wooden members 28 and 30 provide a bearing-reaction surface on the inboard side of the container; the member 28 being fastened to member 30 which in turn is securely ixed to the floor of the container 26.

Restraining the floating wooden foot on the remaining side are two angle irons 32 and 34 which yare slotted to provide for vertical adjustment of the floating foot when the carriage bolts 36 and 37 are loosened. The carriage bolts 36 and 37 are utilized to secure the angle irons to the lateral bearing surfaces. While the angle irons serve tvo entrap the foot, the foot is still permitted lateral and vertical movement.

To restrain the foot in the lateral direction there is a slotted angle iron 40 (FIGURE 2) fastened to the floor of the container 26 by the bolt 42. A wooden spacer 44 provides for pr-oper positioning of the angle. The angle is given `additional support by the steel rod 46 which is mounted directly behind the angle and secured through the angles 32 and 34. This arrangement is the same for both ends of the foot and provides for a minimal protection against longitudinal shock.

Members 48 through 56 provide for a secure mounting means between container wall and oor.

The integral construction of the resilient skid permits varying the thickness and bearing area, by means of the slotted angles, to satisfy a wide degree of shock protection and compensate for varying package weight.

Although the invention has been described with reference to a particular embodiment, it will be understood to those skilled in the art that the invention is capable of a variety of alternative embodiments within the spirit and scope of the appended claim.

I claim:

A resilient skid for shock mounted packaging cornprising: a container; a longitudinal channel consisting of the container side wall extension, container iloor and a restraining wall mounted on the container oor extending longitudinally parallel to and in the same vertical direction as the side wall extension; rubber shock absorbers mounted on each of the three sides of Ithe channel; a first pair of angle irons mounted on the lioor of the container transverse to the longitudinal axis of the channel and at the opposite ends thereof, said first langle irons extending in the same vertical direction as the side wall extension and adapted to act as an end of the channel; bolt means extending through the sides of the channel directly behind said rst angle irons and acting as a support therefor; a second pair of angle irons adjustably mounted on the channel sides and extending along the longitudinal axis so as to partly enclose the open side of the channel; a wooden f-oot member floating Withl in the channel against the buffer on three sides and the angle irons on the fourth side, part of said foot member adapted to protrude from said channel and act as the bearing surface for the container.
